Dissolved in distilled water, copper nitrate gives a clear blue electrolyte for electrolysis practicals. With copper electrodes, copper leaves the anode and builds up as a pink-brown layer on the cathode, so students can weigh both electrodes before and after the run and relate the change in mass to the current and time. The same solution can be used to copper-plate a small, clean metal object in a school chemistry lab.
A dilution series made from one weighed stock solution shows how the depth of blue colour fades as the concentration falls, a simple first step into colorimetry. Copper nitrate picks up moisture from the air, so weigh it quickly and close the container straight after use. It is also an oxidiser and harmful if swallowed: keep it away from combustible materials, wear eye protection and wash hands after handling.
Jain Scientific Equipments Private Limited trades as ScienceLab and sources Copper Nitrate 100 g for schools, colleges, research laboratories and dealers, dispatching it with its MSDS together with the glassware and electrolysis apparatus that are often ordered alongside it. Copper nitrate is treated as an oxidising substance in transport, so please mention the destination country when you ask about export supply. Company background is on the ScienceLab company profile.

Barium Nitrate (Product Code: SCI-646/282) is an analytical reagent grade barium salt used to test for sulfate ions and to show the green flame colour of barium in school and college chemistry laboratories. It comes in a 100 g pack with an MSDS, and because it adds no chloride ions it is the preferred barium reagent when a sulfate test is followed by a silver nitrate halide test on the same sample. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.
| Parameter | Detail |

In qualitative analysis, a few drops of barium nitrate solution are added to the unknown solution after it has been acidified with dilute nitric acid. A dense white precipitate of barium sulfate that does not dissolve confirms sulfate ions. Because the nitrate brings no chloride with it, the rest of the sample can still be tested for halides with silver nitrate.
On a clean wire loop in a Bunsen flame, barium compounds give a pale apple-green colour, so barium nitrate sits in flame test sets for school chemistry practicals next to sodium, potassium and copper salts; the same colour explains its role in green fireworks. Soluble barium salts are toxic if swallowed and barium nitrate is an oxidiser, so students should handle only small, dilute portions under supervision, keep it away from fuels and collect residues for proper disposal.
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which sources Barium Nitrate in 100 g analytical reagent packs for school laboratories, colleges, testing labs and dealers. Buyers equipping a qualitative analysis bench can ask for it together with the acids, glassware and flame test items below in a single enquiry. Read more about the company on the ScienceLab profile page.
Items used alongside barium nitrate in sulfate tests and flame tests:
More reagents and apparatus are listed in the Laboratory Equipment category.
What is Barium Nitrate used for in the laboratory?
Barium Nitrate is used as a test reagent for sulfate ions, which form a white barium sulfate precipitate, and as a source of barium's apple-green colour in flame tests. This listing is analytical reagent grade in a 100 g pack supplied with an MSDS.
Why use Barium Nitrate instead of barium chloride for the sulfate test?
Barium Nitrate adds no chloride ions to the sample, so after the sulfate test the same solution can still be checked for chloride, bromide or iodide with silver nitrate. Barium chloride remains a simpler choice where no halide test follows.
What flame colour does Barium Nitrate give?
Barium Nitrate gives a pale apple-green flame when a little of the salt is held in a non-luminous Bunsen flame on a clean wire loop. The colour is fainter than the yellow of sodium, so it is easier to see in a dimmed room.
Is Barium Nitrate hazardous?
Yes. Barium Nitrate is toxic if swallowed, like other soluble barium salts, and it is an oxidiser that can intensify a fire. Use small quantities with eye protection and gloves, keep it away from fuels and follow the MSDS supplied with the pack.
How long does Barium Nitrate keep?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep Barium Nitrate tightly closed in a dry, locked chemical store, separate from combustible and reducing materials.
Who supplies Barium Nitrate SCI-646/282?

In the cobalt nitrate test, a white residue left after heating an unknown salt on a charcoal block is moistened with a drop or two of cobalt nitrate solution and heated again in the oxidising flame of a blowpipe. A blue mass points to aluminium, a green mass to zinc and a pale pink mass to magnesium, which makes this single reagent a useful step in the salt analysis scheme of school chemistry lab practicals.
Cobalt(II) solutions also show a striking colour equilibrium: pink hydrated cobalt ions turn blue when concentrated hydrochloric acid is added or the solution is warmed, and return to pink on dilution or cooling, a clear illustration of Le Chatelier's principle. Cobalt compounds are harmful, can cause skin and breathing sensitisation and are treated as possible carcinogens, so wear gloves, avoid raising dust and dispose of cobalt residues as heavy-metal waste.
Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies Cobalt Nitrate to schools, colleges, examination centres and dealers that stock reagents for dry salt analysis. For vendor registration, the supplying company is Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597, GSTIN 06AAECJ8618A1ZT). Further company information is on the ScienceLab profile.
Apparatus and reagents that go with cobalt nitrate in dry tests and colour demonstrations:
See the Laboratory Equipment category for other analysis reagents and apparatus.
What is the cobalt nitrate test in salt analysis?
The cobalt nitrate test uses Cobalt Nitrate solution on a white residue from a charcoal-block test; after reheating in the oxidising flame, a blue mass indicates aluminium, green indicates zinc and pale pink indicates magnesium. It is a standard confirmatory step in dry salt analysis.
How much Cobalt Nitrate is in one pack?
Each pack of Cobalt Nitrate SCI-648/283 contains 100 g of analytical reagent grade salt and is supplied with an MSDS. Only a few drops of dilute solution are used per test, so tell us how many students or batches you plan for when asking for a quantity.
Why does Cobalt Nitrate solution change from pink to blue?
Cobalt Nitrate solution is pink because of hydrated cobalt(II) ions; adding concentrated hydrochloric acid or heating forms a blue chloro-cobalt complex. Diluting or cooling reverses the change, which makes it a clear classroom demonstration of chemical equilibrium.
What safety precautions apply to Cobalt Nitrate?
Cobalt Nitrate is harmful, can cause skin and breathing sensitisation, is treated as a possible carcinogen and is an oxidiser. Handle it with gloves and eye protection, avoid dust, keep it away from combustibles and collect all residues as heavy-metal waste.
What is the shelf life of Cobalt Nitrate?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Cobalt Nitrate should be kept tightly closed in a cool, dry place, because the crystals attract moisture from the air.
Who supplies Cobalt Nitrate for school laboratories?
Cobalt Nitrate is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges and dealers in India and international markets, in 100 g analytical reagent packs with MSDS, and it can be quoted together with charcoal blocks and blowpipes.

For the brown ring test, a little potassium nitrate solution is mixed with freshly prepared iron(II) sulfate solution, and concentrated sulfuric acid is poured slowly down the side of the tilted tube. A brown ring where the two layers meet confirms nitrate ions. Running the test first on this known nitrate shows students what a positive result looks like before they try unknown salts.
Dissolving potassium nitrate in water absorbs heat, so a thermometer in the beaker records a clear fall in temperature, an easy way to introduce endothermic change and enthalpy of solution in a school chemistry lab. In a flame test, potassium gives a lilac colour that is best seen through blue cobalt glass, which hides any yellow from sodium traces. The salt is an oxidiser, so store it away from fuels, sulfur and charcoal.
Potassium Nitrate 200 g is sourced and supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, for school laboratories, colleges, training institutes and dealers. It is sent with its MSDS, and because potassium nitrate is an oxidising salt, overseas buyers should state the destination so that suitable transport packing can be discussed. Learn about the company on the ScienceLab profile.
Reagents and apparatus for nitrate ion tests, flame tests and heat-of-solution work:
The Laboratory Equipment category lists further chemicals and glassware.
What is Potassium Nitrate 200 g used for?
Potassium Nitrate 200 g is used as a known nitrate for the brown ring test, as a lilac flame test sample and to show an endothermic temperature drop on dissolving, as well as in solubility work. It is analytical reagent grade and supplied with an MSDS.
How is Potassium Nitrate used in the brown ring test?
Potassium Nitrate solution is mixed with fresh iron(II) sulfate solution, then concentrated sulfuric acid is run slowly down the side of the tube to form a lower layer. A brown ring at the boundary confirms nitrate and gives students a reference result.
Why does the temperature fall when Potassium Nitrate dissolves?
Dissolving Potassium Nitrate in water is endothermic: energy is taken in to separate the ions of the crystal, so the solution cools. Measuring the drop with a thermometer lets students compare it with salts that warm the water as they dissolve.
What flame colour does Potassium Nitrate give?
Potassium Nitrate gives a lilac flame colour in a non-luminous Bunsen flame. Viewing the flame through blue cobalt glass hides the yellow glow from any sodium contamination, which makes the potassium colour much easier to identify.
How should Potassium Nitrate 200 g be stored?
Keep Potassium Nitrate 200 g in a closed container in a cool, dry store away from combustible materials, sulfur and charcoal, because it is an oxidiser. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

When sodium nitrate is heated strongly in a hard-glass or boiling tube, it melts and gives off oxygen, which relights a glowing splint, leaving sodium nitrite behind. No brown nitrogen dioxide appears, unlike the nitrates of lead or copper, so heating the two types side by side is a memorable way to show how thermal stability changes across the reactivity series in a school chemistry lab.
A trace of the salt on a clean wire loop gives the intense, lasting yellow flame typical of sodium, a useful reference colour in flame test practicals. In agriculture and biology labs, sodium nitrate also serves as a soluble nitrogen source in plant nutrition experiments. It is an oxidiser that attracts moisture, so keep the lid tight, store it away from combustibles and clean up spills promptly.
Under the ScienceLab name, Jain Scientific Equipments Private Limited supplies Sodium Nitrate to schools, colleges, agricultural institutes and trade buyers, together with the MSDS for their chemical records. Laboratories building a nitrate comparison set can request this salt with other nitrates from the same catalogue in one quotation. Visit the ScienceLab profile for details about the company.

Explore more items in the Laboratory Equipment category.
What happens when Sodium Nitrate is heated?
When Sodium Nitrate is heated strongly it melts and decomposes into sodium nitrite and oxygen, which relights a glowing splint. Unlike copper or lead nitrate, it gives off no brown nitrogen dioxide, a key point when comparing the thermal stability of nitrates.
What is Sodium Nitrate used for in school labs?
Sodium Nitrate is used in school labs for thermal decomposition comparisons, as a yellow flame test sample, as a nitrate source for ion tests and in plant nutrition experiments. This listing is a 200 g analytical reagent pack supplied with an MSDS.
Is Sodium Nitrate the same as sodium nitrite?
No. Sodium Nitrate contains the nitrate ion and turns into sodium nitrite only when heated strongly, while sodium nitrite is a separate, more toxic chemical with different uses. Check the name and code SCI-653/285 carefully when you order.
What precautions apply to Sodium Nitrate?
Sodium Nitrate is an oxidiser that can make a fire burn more fiercely, and it is harmful if swallowed in quantity. Wear eye protection, keep it away from fuels and reducing agents, and store it in a closed container because it absorbs moisture.
Does Sodium Nitrate have an expiry date?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Sodium Nitrate that is kept sealed and dry stays free-flowing for longer than a pack left open to humid air.

Heated in a dry boiling tube, lead nitrate crystals crackle as they split apart, then give off brown nitrogen dioxide and oxygen, leaving a yellow residue of lead(II) oxide. The experiment illustrates a decomposition reaction and the release of a coloured, toxic gas, so it should be done with a small quantity inside a fume cupboard.
Mixing lead nitrate solution with potassium iodide solution produces a bright yellow precipitate of lead iodide, a classic double displacement reaction. If the precipitate is dissolved in hot water and left to cool, it re-forms as glittering golden plates, often called golden rain. Lead compounds are toxic and can harm an unborn child, so this salt is for teachers or closely supervised older students wearing gloves, with every residue collected as heavy-metal waste rather than poured down the sink.
Jain Scientific Equipments Private Limited sells laboratory chemicals under the ScienceLab name and supplies Lead Nitrate in 200 g analytical reagent packs, each accompanied by its MSDS, to schools, colleges and dealers. Because lead nitrate is both toxic and an oxidiser, it travels as a dangerous good; share the destination and quantity so transport options can be checked before quoting. See the ScienceLab profile for company details.
Items needed for safe lead nitrate decomposition and precipitation practicals:
Find more reagents and apparatus in the Laboratory Equipment category.
What is Lead Nitrate used for in chemistry practicals?
Lead Nitrate is used to demonstrate thermal decomposition, which gives brown nitrogen dioxide and yellow lead oxide, and double displacement with potassium iodide, which forms a yellow lead iodide precipitate. This listing is a 200 g analytical reagent pack supplied with an MSDS.
What is observed when Lead Nitrate is heated?
Heated Lead Nitrate crackles as the crystals break apart, then releases brown nitrogen dioxide gas and oxygen, and a yellow residue of lead(II) oxide remains. Because the gas is toxic, heat only a small amount and do it in a fume cupboard.
What forms when Lead Nitrate reacts with potassium iodide?
Lead Nitrate and potassium iodide solutions react to form a bright yellow precipitate of lead iodide and a solution of potassium nitrate. Recrystallising the precipitate from hot water gives shiny golden flakes, known in classrooms as golden rain.
Is Lead Nitrate safe for students to handle?
Lead Nitrate is toxic, may damage fertility or an unborn child and is an oxidiser, so it should be used only in small amounts under teacher supervision with gloves and eye protection. Follow the MSDS and dispose of residues as heavy-metal waste.
How should Lead Nitrate be stored?
Store Lead Nitrate in a closed, labelled container in a locked chemical cabinet, away from combustible materials and food areas. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

In the azo dye test for primary aromatic amines, the amine is dissolved in dilute hydrochloric acid and chilled in ice, then cold sodium nitrite solution is added to form a diazonium salt. Pouring this into an alkaline solution of a coupling agent such as 2-naphthol gives a vivid orange-red dye that confirms the amine. The same diazotisation step underlies dye synthesis practicals and colour tests based on sulfanilic acid.
Gently warming a solution of sodium nitrite with ammonium chloride releases nitrogen gas, which can be collected over water to study an unreactive gas. Sodium nitrite is toxic if swallowed and a strong oxidiser, so never grind or heat it dry with ammonium salts. Store it apart from acids, which release toxic nitrogen oxides, and label it clearly so it is not confused with sodium nitrate or common salt.
ScienceLab is the trade name of Jain Scientific Equipments Private Limited, which supplies Sodium Nitrite in 100 g analytical reagent packs, each with its MSDS, to universities, colleges, pharmacy institutes and laboratory dealers. For buyers completing supplier registration, the company's Importer-Exporter Code is AAECJ8618A (DGFT) and its GSTIN is 06AAECJ8618A1ZT. The ScienceLab profile has more about the company.
Reagents used with sodium nitrite in diazotisation and gas preparation work:
Further chemicals and apparatus are in the Laboratory Equipment category.
What is Sodium Nitrite used for in the chemistry lab?
Sodium Nitrite is used with cold dilute hydrochloric acid to make nitrous acid for diazotising aromatic amines, in the azo dye test and dye preparation practicals, and with ammonium chloride to generate nitrogen gas. This listing is a 100 g analytical reagent pack with MSDS.
Why must diazotisation with Sodium Nitrite be kept cold?
Diazotisation with Sodium Nitrite is carried out in an ice bath because diazonium salts decompose quickly when warm, releasing nitrogen and spoiling the dye test. Keeping both the amine solution and the nitrite solution cold gives a clearer colour result.
Is Sodium Nitrite hazardous?
Yes. Sodium Nitrite is toxic if swallowed, an oxidiser that can intensify fires, and it releases toxic nitrogen oxides with acids. Use it with gloves and eye protection, weigh it away from food and drink, and follow the MSDS that comes with the pack.
How is Sodium Nitrite different from sodium nitrate?
Sodium Nitrite contains the nitrite ion and acts as a source of nitrous acid, while sodium nitrate contains the nitrate ion and works mainly as an oxidiser. The two white salts look alike, so store them with clear labels to prevent mix-ups.
How should Sodium Nitrite be stored, and how long does it last?
Store Sodium Nitrite tightly closed in a cool, dry, locked cabinet away from acids, ammonium salts and combustibles. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

The best-known teaching use of nitrobenzene is its reduction to aniline: the liquid is heated under reflux with granulated tin and concentrated hydrochloric acid, the mixture is made alkaline, and the aniline is separated by steam distillation. Students also use a small sample as a reference compound when learning how benzene is nitrated and how a nitro group changes reactivity in electrophilic substitution.
Because nitrobenzene does not mix with water and sinks below it, it shows clearly how a separating funnel divides two liquid layers. It is toxic by inhalation, by swallowing and through the skin, and is suspected of causing cancer, so work only in a fume cupboard with chemical-resistant gloves and eye protection. Keep the bottle closed and away from heat and oxidising agents.
Jain Scientific Equipments Private Limited, trading as ScienceLab, sources Nitrobenzene for universities, engineering and pharmacy colleges, research laboratories and chemical dealers, and sends it with the MSDS needed for safe handling. As a toxic liquid it needs dangerous-goods packing for transport, so share the delivery location when asking for a quotation. The ScienceLab profile describes the company.

Browse the Laboratory Equipment category for other organic reagents and glassware.
What is Nitrobenzene used for in the laboratory?
Nitrobenzene is used in organic chemistry teaching and research to prepare aniline by reduction with tin and hydrochloric acid, as a reference compound for nitration and aromatic substitution, and to demonstrate immiscible liquid layers. This listing is a 250 ml analytical reagent pack with MSDS.
How is aniline made from Nitrobenzene?
Aniline is made from Nitrobenzene by heating it under reflux with granulated tin and concentrated hydrochloric acid, then adding alkali and steam-distilling the aniline. The practical should be carried out by trained students in a fume cupboard with full protective equipment.
Is Nitrobenzene toxic?
Yes. Nitrobenzene is toxic if inhaled, swallowed or absorbed through the skin, can damage organs with repeated exposure and is suspected of causing cancer. Handle it only in a fume cupboard with chemical-resistant gloves and eye protection, following the MSDS supplied.
Does Nitrobenzene float or sink in water?
Nitrobenzene sinks in water because it is denser, and it does not mix with water, so it forms a separate lower layer. This makes Nitrobenzene a clear example for teaching liquid-liquid separation with a separating funnel.
How should Nitrobenzene 250 ml be stored?
Store Nitrobenzene tightly closed in a cool, ventilated, locked chemical store away from heat, flames and oxidising agents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
